FENCE-WEAV|NG MACHINE.

SPECIFICATION forming part of Letters Patent No. 746,139, dated December 8, 1903,

Application filed March 17, 1903- cation.

My invention relates to improvements in fence-weaving machines; and the object of the invention is to devise a machine of this class which will be simple and cheap to manufacture and also will be simple and easy to operate, be durable, be not liable to get out of order, and will weave more tightly and accurately than other machines of the same class at present in use; and it consists, essentially, of a vertical bar provided with a series of holding-brackets, through the jaws of which the strand-wires of the fence pass, and an arm pivotally secured on a slidable bracket on such vertical bar and carrying the weaving-wheel, through which the vertical stay-wire passes,.suoh weaving-wheel being rotated by a bevel gear-wheel journaled on the arm and operated through a crank, the parts being otherwise arranged and constructed in detail, as hereinafter more particularly explained.

Figure 1 is a perspective view showing a portion of a fence with my machine in the working position. Fig. 2 is a sectional plan through the working arm. Fig. 3 is a perspective view of the working arm from the operating side. Fig. 4 is a perspective view from the opposite side. Fig. 5 is a sectional detail of the weaving-wheel.

In the drawings like characters of reference indicate corresponding parts in each figure.

A represents the longitudinal strand-wires of the fence.

B represents the stay-wires, and O is the upright bar,which is made, preferably, of a T- angle bar and has secured thereto the brackets 0, provided with end jaws c and split pins 0 extending through the ends of the jaws. The brackets c are held on the upright bar 0 by screws 0 The upper and lower brackets c are provided with extensions 0 and guiding-notches 0 such extensions extending relatively to the opposite side of the bar and being designed to hold the upright C in a subfierial No. 148,213. (No model.)

stantially vertical position. The jaws c are fitted onto the strands A and the split pins 0? inserted in the outside of the jaws 0, so as to hold the bar in position.

D is the working arm, which is pivoted on.

the pin (1, held in the bracket (1, which is provided with guideways d at each side, whereby it may be capable of vertical adjustment on the bar 0. The arm D is provided with a handle D.

E is a bevel gear-pinion having a hollow hub e, such hub extending through a journal D forming part of the arm, D. The pinion E and hub e are provided with a slot e at one side, such slot extending longitudinally through the hub and wheel, as indicated. The journal D is provided with guidingplates D which are separated apart corresponding to the width of the slot e in the hub e and wheel E. the plates flare, and this is for the purpose of providing an easy ad mission of the strandwire A into the hub.

The hub e is provided with a broad arcshaped internal annular recess e which is designed to allow of the strand-wires to pass freely thereonto as the working arm is being moved onto the strands of'the fence, particularly where coiled wire is employed for the longitudinals.

It will be noticed that The stay-wire B is wound in a spool, which is journaled on an arm 1), attached eccentrically to the face of the gear-wheel. The wire B is thus arranged to pass eccentrically through the hollow hub e, and at the forward end it passes through a thimble F, eccentrically placed and provided with arms f, whereby it is attached to the disk G, secured on the threaded end of the. hub by screws, the holes for which are partly in the disk and partly in the hub to prevent the disk from turning.

It will be noticed that the thimble F is pro-. vided with three arms, which are set equidistant apart, so that the distances of the sleeve may be changed circumferentially and reversed in order to provide for the wear, as of course the wear would ordinarily come upon the inner edge of the thimble, and by turning it and reversing it the wear may be distributed evenly without having to provide a new thimble.

The beveled gear-pinion E is driven from a beveled gear-wheel H, which is seen red on the end of the stud-shaft 7L, journaled in the arm D and provided with a crank-handle h.

It will be noticed that the bevel-Wheel H is set at an obtuse angle to the bevel-pinion E, and consequently I am enabled to get a larger ball or spool of wire for the stays B, and thereby I am enabled to weave a greater number of stays from the one ball.

The disk is provided with a slot g, which registers with the slot 6 in the hub e. The disk G is also provided with a notch g, as indicated, and the disk is so formed as to have an overhang 9 which extends over or beyond one of the sides of the notch g.

The arm D is provided with a slot 2 at one end, and through this slot extends the end of the lover I, which is pivoted on the stud 2', attached to or forming part of the arm D. The opposite end of the lever 1 lies in proximity with the handle D.

The lever ll has a lateral projection i, which normally engages with the bell-crank J when the end of the lever 1 extends into the notch g. The bell-crank J is pivoted on a stud j on the arm ii and is provided with a raised portion j, underneath which the lever extends. lhe lover I is also provided with a projection which is encircled by a spiral spring 1 such spring extending between the lever and the opposite end of the bell-crank J, as indicated in Figs. 8 and The Wheel H is provided with a cam projection ii, and such wheel is proportioned relatively to the pinion E in the proportion of three to two that is to say, that on every two turns of the Wheel H the pinion E will give three turns.

Having now described the principal parts involved in my invention, 1 shall briefly describe its open-ttion and utility. The bar 0 is placed upright against the strands and the jaws are placed so as to grasp the strands, such strands being held in the jaws by means of the split pins. starting at the top strands, a plier or other suitable instrument is used for bending the top of the stay-wire onto the top strand, the arm being placed close to the strands. ihe handle D is grasped by one hand and the cranlrhandle la is turned once, the workman being careful at the same time to hold the outer end of the lever I, so as to hold the inner end thereof out of the notch g. The stay-wire B is thus twisted, by means of the eccentrically-placed thimhle F, around the longitudinal strand, and as soon as the workman has turned the handle it one turn he lets go of the lever I and then gives the handle another turn, whereupon the inner end of the lever I will, when the disk G turns around in the direction indicated by arrow, drop into the notch g, the overhanging part serving to prevent the end of the lever passing the notch. Of course the lever 1 is forced in by the spring ll hen the lover I has passed into the notch g, it will be seen means that the slot g comes opposite the slot e in the hub e, and consequently the arm may be pulled outwardly from the strand and then allow it to drop on its guiding-lnacket cl upon the bar O to the next strand, when the arm maybe thrown inwardly again over the next strand. In order to relieve the lever from the notch, and thereby permit the wheel E to be turned, it will be seen that the outer end of the lever is pressed inwardly by hand, so as to withdraw the inner end from the notch. The handle 7t is now turned, and at the same time the end of the lever is grasped, so that the innerend is held out from the notch g. When the lever is thrown out, necessarily the long arm of the bell-crank J is turned so that the projection c" of the lever is Within the raised portion j and almtting the depressed portion of the arm. After the disk G turns once past the inner end of the lever the handle 7t is released, so that when the cam H is brought around again such cam strikes the long arm of the bell-cran k J, th rowing it forward ly, and thereby causing the spring I to act against the inner end of the lever, so as to press it against the periphery of the disk. It will thus be seen that as soon as the disk turns around sufliciently the inner end of the lever will spring into the notch g, and thus hold the slot 9 opposite the slot 6 preparatory to Withdrawal from the longitudinal strand. At the same time, of course, the treble twist is given to the stay-wire.

What I claim as my invention is l. In a device of the class described, a

frame, a rotary slotted hub journaled there in, a wire-spool carried by said hub having the free end of the wire passing eccentrically through the hub, means for rotating said hub, a locking-lever designed to hold said hub against rotation, a device for holding said lockinglever out ofloeking action, and means for automatically operating said holding devices to release the locking-lever after the hub has niadea certain number of rotations, substantially as described.
